You wont find much better value than Max and Naiyana's place! Very clean, modern, and well maintained. Communication was fast and easy, which was appreciated in a city like Bangkok.
Their condo is a 10min brisk walk to the nearest station, but it's more convenient to use grab anyways. Make sure to use the shuttle service if you want to go to Terminal 21.
If you do walk, their condo is close to laundry services, ATMs, 7/11, and restaurants; all just down the street!
